wget command on same file works!
downloading from an AWS S3 bucket works using duck CLI and Amazon S3 duck protocol.
I believe https is not a protocol. WebDAV (HTTPS) protocol does not work in this case.
The issue here is that we are a WebDAV client and attempt to read file attributes using the PROPFIND method. We do have however a fallback implemented for interoperability for downloads with regular HTTP servers to use HEAD when PROPFIND fails with 405 Method Not Allowed shown below.
